title: [Effect of the deficiency of histone structural genes on their amount in Drosophila].
abstract: The amount of histone structural genes was determined in heterozygotes for two different deficiencies of the histone locus of the 2nd chromosome. In case one chromosome lacks histone genes, the number of histone structural genes in the normal homologous chromosome is likely to increase by means of magnification and compensation in the same way as in the case of rRNA genes.
